HOSE-"COUPLING.

SPECIFICATION forming part of Letters Patent N0. 764,395, dated July 5,1904. Application filed September 8, 1903. Serial No. 172,258. (Nomodel.)

To all whom it may concern.-

Be it known that we, FREDERICK Swnnn and GEORGE L. FARNSWORTI-I,citizens of the United States of America, residing at Turtlecreek, inthe county of Allegheny and State of Pennsylvania, have invented certainnew and useful Improvements in Hose-Couplin gs, of which the followingis a specification, reference being had therein to the accompanyingdrawings.

This invention relates to certain new and useful improvements inhose-couplers; and the object of the invention is to provide novel andeffective means for quickly and securely joining the two sections ofhose.

Briefly described, our invention comprises I two substantially similarmembers, each of which is adapted to have a section of the flexible hosesuitably secured thereto. These sections or members are each adapted toreceive a nipple end of a sleeve which is interposed between the twosections or members and has an annular flange or ring adapted to beengaged by the catch-bars carried by the respective sections or members.These catchbars are moved out of engagement with the annular flange orring, preferably by the employment of a spreader, which is left on themembers when the latter are in theuncoupled position. 7

In describing the invention in detail reference is had to theaccompanying drawings, forming a part of this specification, and whereinlike numerals of reference indicate like parts throughout the severalviews, in Which- Figure 1 is a side elevation of our improvedhose-coupler in the coupled position. Fig. 2 is a longitudinal sectionalview thereof. Fig. 3 is a transverse vertical sectional view.

In the accompanying drawings, 1 and 2 indicate the'socket members orsections, each of which has a corrugated nipple or extension 3 toreceive the flexible hose (not shown) adapted to be suitably secured tosaid nipple or extension ends. These socket members are adapted toreceive in their outer ends the nipple ends 4 of the sleeve 5, the endsof the socket members fitting against the annularshown.

shoulders or seats 6 of the sleeve and the sleeve being provided with acentrally-arranged peripheral flange or ring 7. Catchbars 8 are securedto opposite sides of the socket members 1 and 2, being secured by screwsor pins 9, which pass through the catch-bars, near the outer endsthereof, and through spacing-blocks 10, interposed between theeatch-bars and the socket members 1 and 2. The catches 11 of thesecatch-bars are adapted to engage over the annular flange or ring 7.These catch-bars are made of material having suflicient spring to permitthe catches being disengaged from the annular ring or flange, and thisdisengagement may be efiected by inserting a suitable instrumentunderneath the catch-bars to pry the catch out of engagement; but wepreferably employ a spreader-ring 12, made circular in shape, withhandles 14: at opposite sides of its periphery, and these spreader-ringsare adapted to lie on the socket members 1 and 2, as Thesespreader-rings are provided on opposite sides with cams 12, and therings are prevented from longitudinal movement on the socket members byheaded screws or pins 14. in the socket members at each side of thespreader-rings. By turning the spreader the cams 12 engaging against thecatch-bars lift the catches out of engagement with the ring or flange 7,whereby to permit the disengagement of the sections forming the coupler.

While we have shown and described our invention as it is practiced byus, yet it will be obvious that various changes may be made in thedetails of construction without departing from the general spirit of ourinvention.

Having fully described our invention, what we claim as new, and desireto secure by Letters Patent, is-

1. A hose -coupling consistingof a sleeve having a centrally-arrangedring thereon and socket members engaging over each end thereof, catchesarranged on the socket members the catches of one socket member engagingon one side of said ring and the catches of the other socket memberengaging on the other side thereof, with rings surrounding said socketmembers and having cams arranged on its periphery to disengage saidcatches, with means on each side of said ring carried by the socketmember to prevent lateral movement of the rings.

2. A hose-coupling comprising a sleeve having a centrally-arranged ringthereon, socket members received on the opposing ends of the sleeve,catches carried by the socket members for engagement With said ring, thecatches of one socket member engaging on one side of the ring, and thecatches of the other socket member engaging on the opposite sidethereof, rings mounted one on each socket member intermediate the frontand rear ends of said catches, with cams FREDERICK SWEED.
